Approximate methods for pile design calculations
From introduction: "At a certain stage in the design of a pile there come a time when it is urgent to obtain day to day answers on the effects of various changes in the design parameters... It is hoped that the procedures described in the present memo will serve as a bridge between the crudest diffusion theory calculations and the more elaborate multi-group methods."

Balanced Ionization Chamber for Differential Measurements of Gamma Rays
"The purpose of the work was to develop a method of measuring very small differences in the half lives of gamma ray emitting radioactive substances. The apparatus was then used to try to detect a difference in the half lives of Be7 metal and BeO. The results of the measurements on the two different chemical forms of beryllium will be given" (p. 1).

Criticality in graphite systems
From introduction: "The use of graphite in the collectors for the electromagnetic process results in the need for storage and processing of masses of U-235 contaminated carbons. Because of the widely differing moderating properties of carbon hydrogen, it was necessary to employ a modified thermal diffusion method to determine critical conditions, applicable to the Y-12 chemical cycle. It can be shown that the following treatment is basically the same as that used by X-10 in one-group pile calculations."
